SPECIFICATION forming part of Lettcrs Patent No. 292,877, dated February5, 1884.

' Application filed May 28,1583. (No model.)

To all whom, it may concern:

Be it known that I, FRANK '1. VERIIAREN, residing at Spencer, in thecounty of Clay and State of Iowa, and a citizen of the United States,have invented new and useful Improvements'in Cultivators, of which thefollowing is a full description, reference being had to the accompanyingdrawings, in which- Figure l is a top or plan view, showing the arch,draft-bars, guide-rod, wheel-spindles, and beam-coupling of a tonguelesscultivator. with the drag-bar and its actuating device and the arms forhanging up the beams; Fig. 2, a side elevationof the parts shown in Fig.1, showing in dotted lines the position of the wheel; Fig, 3, a detailof the devices for raising and lowering the drag-bar; Fig. 4, a detail,being a rear elevation of one side with the pipe-box partly in section.

Itis customaryto use what are termed dragbars or runners withcultivators, for the purpose of furnishing a support for the beams andremoving the strain from the beam-coupling and the wheel-spindle inmoving the cultivator from place 'to place, with the plowbeams elevated.Heretofore such drag-bars have been applied by being removably attached,so as to be taken off and placed in position to rest on the ground whenthe beams are elevated, or in position to lie above the ground when thebeams are in use, and they have been pivoted so as to be raised orlowered, as required, to be out of use or in use; but in every case thisraising and lowering of the drag-bar has to be performed by theoperator, who makes the changes as he requires the drag-bars to beacting or non-acting.

The main object of this invention is to ap- I ply drag-bars to acultivator and have them broughtinto position for use as the beams areelevated, or thrown up out of use as the beams are lowered, and haveboth movements performed automatically by the act of elevating orlowering the beams; and its nature consistsin the devices andcombinations hereinafter described, and pointed out in the claims, foraccomplishing the object stated;

In the drawings, A represents an arch or frame, having an upper orhorizontal portion, a, side or vertical portions, a, and lower horidleor bearing a of the arch or frame,and

forming the horizontal pivot to allow of vertical movement of the beam.

0 are clasps or. coupling-boxes, one located on each pipe-box B, andeach having a rearwardly-projectiug flange or portion, 0, for theattachment of the forward end of the plowbeam, by passing a pin or boltthrough the coupling on the end of the beam and a hole in the flange 0,and by having also ears or lugs c at the front side, through which atightening-bolt, 0, passes, for drawing the parts of the clasp orboxingfirmlydown upon the pipebox, so i as to be immovable thereon. Thisclasp or box may be of the form shown and described, or of any other ofthe well-known forms for attachment of the forward end of the beam tothe pipe-box, and the beams are adjusted in or out by unloosening thebolt 0 and slipping G on the pipe-box until the de sired position isreached, and "then securing it by the tightening-bolt c.

D are heads or supports, one secured in any firm manner to each end ofthe spindles a. Each head or support has a rearwardlyextending arm, (I,and is provided on its outer face with 'projecting ears (1, in the formof construction shown.

E represents the drag-bars, each having at its lower end a flat portion,(2, standing at the proper inclination to themain portion to rest flat,or nearly so, on the ground, when the beam is lifted. The upper end ofeach dragbar is turned at right angles, or nearly so, to the main orbody portion, to form a short arm, a. This short arm 6 has pivotedthereto one end of a link, 0, the other end of which is pivoted to theend of the arm I), projecting out from the pipebox B, and the upper endof the drag-bar is pivotally connected to the end of the arm (I of thehead or support D.

F are arms or supports pivoted at or near their forward ends, one toeach of the vertical portions of the arch or frame, by a pin or pivot,f. The forward end of each arm or support F has pivoted thcretothe upperend of a link, f, the lower end of which is pivoted to the end of anarm, 0, projecting out from the pipe-box B.

G is a guide rod or bar, having an upper horizontalportion, 9, side orvertical portions, 9, and lower horizontal portions, the ends of whichhave a downward turn.

H represents the draft-plates, one on each side of the cultivator, andeach pivoted at its inner end between the ears (1, by a pin or pivot, h,and each having an eye or socket plate, h, to receive the downward-proecting ends of g and form a connection between the two plates, by whichthey will be moved in unison.

I are wheel-spindles, one secured to the inner end of each draft-plateH, and projecting out therefrom to receive the wheel.

It will be noticed that the coupling or pipe box B is connected by thelink 0 with the arm c of the drag-bar E, which drag-bar is pivoted tothe end of the arm (Z at its upper end, so that it will remain in astationary position at such upper end. The result of this constructionis that any movem cnt communicated to the pipe-box by the verticalmovements of the plow-beam will be communicated through the arm b, link0, and arm 0 to the drag-bar, and the arm I), link 0, and arm 6 are insuch relation to each other and to the boxing O and the plow-beam thatan upward movement of the plow-beam raises the arm I), throwing down thearm 6, and with it the drag-bar, while the downward movement of theplowbeam throws the arm b down and raises the arm 6 and with it thedrag-bar. 7

It will also be noticed that any movement of the pipe-box B by theraising or lowering of the plow beam will be communicated through thearm I) and link f to the arm or support F, and this arm I) and link fare arranged in such relation to the plow-beam and the arm or support Fthat an upward vertical movement of the plow-beam throws the arm orsupport F down in position to hang the plow-beam thereon, while thedownward vertical movement of the plow-beam throws the arm F up where itwill be out of the way.

The plow-beam is to be provided with a hook, by means of which it can behooked over or 'onto the arm or support F and beheld in this suspendedposition. V

The devices for throwing the drag-bar down as the beam is elevated andraising it as the beam is brought down in position for use can be variedsomewhat from the form and an rangement shown, so long as they will actto give the required movements to the drag-bar from the movements of theplow-beam, and it is not necessary for the operation of the dragbar thatthe arm or support F should be movable also, as this arm or supportmight be staproduces a contrary movement for the dragbar, so that itwill be' brought into use or thrown out of use as the beam is elevatedor lowered.

What I claim as new, and desireto secure by Letters Patent, is asfollows:

1. A drag-bar or runner and a connection therefor with a plow-beam, bywhich move ments of the plow-bcam vertically will produce a reversemovement to the drag-bar, substantially as and for the purposesspecified.

2. A drag-bar, E, pivoted at its upper end and provided with an arm, e,in combination with a link, 0, and arm I), actuated by the movements ofthe plow-beam for raising andlowering the drag-bar, substantially asspecified.

3. A drag-bar, E, pivoted at its upper end and provided with an arm, 0,in combination with the link 6, arm b, pipe-box B, and a plow-beamattached to the pipe-boX, for automatically raising and lowering thedragbar, substantially as specified.

4. An arm or support, F, and a connection with a plow-beam and devicesconnecting the beam with the arm or support, for automaticall yoperating the arm or support as the beam is raised or lowered,substantially as and for the purpose specified.

5. An arm or support, F, link f, and arm I), operated from theplowbeam-, for automatically raising and lowering the arm or support F,substantially as and for the pur poses specified.

6. An arm or support, F, and link f, in combination with the arm I) andpipe-box B, having a plow-beam attached thereto, for automaticallyoperating the arm or support by the movements of the plow-beam,substantially as and for the purposes specified.

7. An arm or support, F, link f, arm I), pipe-box B, arm I), link 6, arm6, and dragbar E, in combination with a plow-beam attached tothepipe-box, for automatically operating the arm or support and thedrag-bar by the movements of the plow'beam, substantially as and for thepurposes specified.
